ASSERTION FAILED: !isSuspended() in WebCore::DOMPromise::promise() in
ReadableByteStreamController::handleSourcePromise()
https://bugs.webkit.org/show_bug.cgi?id=313526
Reviewed by Youenn Fablet.
308984@main replaced algorithmPromise.whenSettledWithResult() with
DOMPromise::whenPromiseIsSettled(.., algorithmPromise.promise(), ...) in
ReadableByteStreamController::handleSourcePromise(). whenSettledWithResult()
returns early if isSuspended(), but algorithmPromise.promise() asserts
!isSuspended().
Check isSuspended() and retrun early before algorithmPromise.promise() in
ReadableByteStreamController::handleSourcePromise().
